This block, known as the “Folsom Wedge 4” was collected in 1963 by ENMU to save this particularly rich area for further analysis. It was opened in the 1990s to check for integrity and yielded a Folsom point at the edge of the plaster jacket. Dr. Kilby’s geoarchaeology class will help excavate and analyze the sediment over the coming semester.
The block was not re-sealed after examination as there was no attempt to move it. The dessicated fine silt has slowly fallen away from the opening exposing at least two bones. Further movement of the block would have caused the sediments to further crumble and fall out of the jacket. In order to hold in the sediment and exposed bone, the block was misted with distilled water, covered with plastic wrap, and sprayed with expanding insulating foam. This was done in two stages over two days in order to prevent sagging of the foam. This method is used to move blocks of sediment or bone from the field to the lab. It is a little sloppy and course but is easier (and far more expensive) than plaster. GTC
